Add an initial revision of an audio server.

Add a functional skeleton for a Motown audio server.  Currently, the server
allows clients to create and configure AudioTracks, and push packets of audio
information to the tracks.  The mixer will mix for multiple outputs, and there
is a many to many relationship between tracks and outputs.  Right now, there is
only a single, generic, audio output implementation whose job in life is to
proved backpressure for audio track pipelines when no other outputs are present.
